Widin Carbide Drills Solid 3xD AlTiN Coated - 11.7mm are precision drill bits built from solid carbide, designed for engineers, fabricators, tradespeople, and serious DIYers who value durability and consistent results. The AlTiN coating adds high heat resistance and reduces friction, helping chips evacuate smoothly and keeping cutting edges sharp across demanding drilling tasks. The 3xD length balances rigidity and versatility for a wide range of depths.

• Solid carbide construction: Built from solid carbide for exceptional hardness and durability, delivering long tool life and consistently reliable performance.
• AlTiN coating for heat and friction control: The AlTiN coating provides high heat resistance and reduces friction, promoting efficient chip evacuation and reduced tool wear.
• 3xD length for rigidity and versatility: The 3xD length balances stiffness and flexibility, enabling reliable drilling across a wide range of depths with minimal deflection.

Together, these features translate into reliable performance, cleaner holes, and fewer interruptions in your workflow. The 11.7 mm diameter fits a wide range of common hole sizes, while the carbide core and AlTiN coating maintain sharpness under demanding speeds. Built for durability and consistent results, this drill minimizes downtime and helps you finish projects with confidence.
